一、纠错的基本原理 在海明码校验中,是将k位信息位,经编码后,形成r位校验位,组成n=k+r位的码子。尽管字长是n,但它是由k位信息经一定的编码得来的。因此对一个n位字长的码子u,都可以用k个线性无关的n维向量,线性组合 First, the basic principles of error correction Hamming code verification, the k-bit information bits, after encoding, the formation of r-bit parity bits, composed of n = k + r-bit code. Although the word length is n, it is encoded by k bits of information. Therefore, for an n-bit word length code u, we can use k linearly independent n-dimensional vectors, linear combination
